NAUI Dive Center Code of Ethics
|
|
|
As a NAUI Worldwide Affiliate Member and scuba diving center operator, I promise
to strictly adhere to the following guidelines:
|
|
|
- Commitment to the student – My first duty is to student safety and the promotion
of Dive Safety Through Education
- Commitment to the aquatic environment – I will instill by instruction and example
respect for and a desire to preserve the aquatic environment.
- Commitment to the profession – I will continually strive to raise professional standards;
accurately represent our qualifications, services offered, and business and teaching
experience.
- Commitment to quality practices – I will sell, rent or provide breathing gases only
to appropriately certified divers; assure that all rental regulators are well maintained
and equipped with submersible pressure gauges and extra second stages; inspect all
rental cylinders in accordance with Professional Scuba Inspectors, Inc. (PSI) and
Compressed Gas Association (CGA) standards and require evidence of inspection decals
be affixed before refilling; have a sample of dispensed breathing gases tested quarterly
to meet or exceed NAUI’s published Modified CGA Grade E Air standard or CGA Grade
E Air standard (as appropriate), and a record of the test results kept on file.
- Commitment to the community – I will dedicate myself to promoting a positive image
within my local community.

NAUI Affiliate members pledge to practice their profession according to the highest
ethical standards. They recognize the right of individuals with the requisite skills
and physical capacity to receive instruction and purchase diving services without
discrimination as to race, sex or beliefs.
